BOAT.

Specicaton. of Letters Patent.

Patented Apr. 14;, 1914.

Application led February 1, 1913. Serial No. 745,694.

To all whom it may concern Be it known that I, ORVAR Gr. B osiNe, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented new and useful Improvements in Boats, of which the following is a specification.

This invention relates to boats, the object of the invention being to provide a boat of the catamaran type, the construction of which will enable the boat as a whole to be easily propelled through the water with a minimum amount of resistance, and which may be easily handled in rough water, ren' dering the boat more steady and sea-worthy than boats of ordinary construction now in common use.

The boat contemplated in this invention is especially designed for fishing and hunting, and may be easily propelled in either direction, without the necessity of turning the boat around in narrow pla-ces.

One of the chief objects of the invention is to provide a boat of the type referred to which will overcome, to a considerable eX- tent, the drag which has heretofore existed in boats of the catamaran type, at the same time enabling the boat to be more easily turned.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.

In the drawings: Figure 1 is a plan view of a boat embodying the present invention. Fig. 2 is a side elevation thereof. Fig. 3 is a cross section taken centrally of the same, Fig. 4 is an enlarged detail section through portions of the floats and deck showing means for detachably connecting said parts.

The boat contemplated in this invention is of the catamaran type, in that it comprises twin fioats l arranged at a suitable distance apart and connected by a deck :2 which is supported upon the floats and forms a bracing connection between them, so that they have a fixed relation to each other. Each of the floats, as shown, is plan0convex in plan view, as clearly illustrated in Fig. 1, the convex sides of the floats being arranged away from each other, while the inner sides of the floats, which are substantially straight throughout their length, are

parallel to each other, thereby forming a parallel runway for the current of water passing between the floats. This overcomes a good portion of the drag or resistance ordinarily presented by boats of the cataw maran type.

In order to further carry out the idea of relieving the drag and resistance, the end portions only of the inner sides 3 of the floats are flared outwardly toward the stem and stern, as shown at 4f, so that when the boat is propelled in either direction, the water passing between the floats will be more readily liberated and permitted to meet the water which is flowing along the outer conve-X sides 5 of the floats.

In the preferred embodiment of the invention, the top and bottom sides of the floats are parallel and without shea-r, but it is, of course, within the scope of this invention to give any desired shear to the tops and bottoms of the floats, as may be found desirable in practice.

The deck preferably extends to the outer sides 5 of the floats, and is surrounded by an upstanding coaming 6, enabling fishing tackle2 hunting paraphernalia, and other material to be placed upon the deck, there by preventing the same from becoming dislodged andfalling overboard.

7 designates a seat supported at a suitable elevation above the deck, and the tops of the floats, by means of legs or braces 8 secured in any convenient manner to the seat and deck.

It is intended to use a double paddle with the boat hereinabove described, the operator placing himself on the seat 7 and manipulating the double paddle while facing in either direction. As the boat is of the same shape at both ends, it is evident that it may be propelled in either direction,

thus avoiding the necessity of turning the boat around in narrow places, and especially in marshes, it being necessary only for the operator to reverse his position on the seat to accomplish this.

While the boat is particularly desirable for hunting and fishing purposes, it will be apparent that the boat may be put to any use which may be found desirable by the owner. It will also be understood that the floats may be made of any desired length, width and depth, according to the desired carrying capacity of the boat as a whole, without departing from the principle or sacrificing any of the advantages of the in- Yventon. The floats rest upon the water throughout their entire length, and thus enable the boat to be very easily handled in a rough sea.

To provide for detaching the deck from the floats, metal straps 9 may be secured to the tops of' the floats at suitable points, as indicated in Fig. l, the straps being secured to the floats by means of bolts or 'rivets 10 and having their opposite ends turned upwardly to form bolts 11 which are threaded to receive nuts l2 screwed thereon and bearing against the top of the deck 2. By removing' the nuts 12, the deck may be detached from the floats, leaving thestraps 9 on the floats.

What is claimed is:

A boat comprising two floats having their major axes parallel to each other, an imper- Copies of this patent may be obtained for ve 4cents each,V byaddressing the forate deck`supported on and connecting said floats, said deck extending transversely across both floats flush with the outside edges thereof and terminating in a fore and aft direction short of the bow and stern of said floats, a seat supported at an elevation above the deck and floats, and metal straps running in a fore and aft Vdirection and fastened to the tops of the floats Hush therewith and having: V their opposite eX- tremities bent upwardly and extended through said deck, said upturned extremities beingthreaded to receive nuts,

In testimony whereof'l affix my signature in presence of two witnesses.
